Structure• The Belgian context• ‘Security of supply’ has two dimensions: follow peak
demand & avoid excessive overproduction (intermittent RES)
• ‘No Policy’ scenario; not sustainable• ‘Security of supply’ scenarios ; new assets, old
thermal assets, DSM & combinations• Surplus risk assessment• Conclusions

RM in ‘No Policy’ scenario
![Page 11: The price of energy security in depressed electricity markets; the case of Belgium](https://reader035.vdocuments.us/reader035/viewer/2022062807/56815037550346895dbe3403/html5/thumbnails/11.jpg)
Supply scenarios for Belgium
• Policy options; incentives for flexible generation (new and old termal), DSM, CFD for RES (with/without Market Participation (MP))
• Investment and system cost of policy options? (with 8% discount rate, LCOE-approach)
• Assumptions on context; peak demand + 0,5%/yr, carbon price up to € 40 per ton CO2 in 2030, endogenous price model (more RES -> lower wholesale prices), network costs increase with RES share

Security of supply; RM > 5% at all times• IF (‘No Policy’ RM < 5%) THEN model triggers CCGT,
OCGT & Biomass investments• Context: old thermal, DSM, BAU RES and High RES
![Page 17: The price of energy security in depressed electricity markets; the case of Belgium](https://reader035.vdocuments.us/reader035/viewer/2022062807/56815037550346895dbe3403/html5/thumbnails/17.jpg)
New capacity; split up
![Page 18: The price of energy security in depressed electricity markets; the case of Belgium](https://reader035.vdocuments.us/reader035/viewer/2022062807/56815037550346895dbe3403/html5/thumbnails/18.jpg)
Incentive schemes
• Capacity payments for CCGT (€ 900/kW), OCGT (€ 700/kW) and Biomass (€ 1050/kW)
• RES support per MWh (incl. Biomass) ; CFD = LCOE minus price
• CFD-MP includes curtailment (max 5% PV, max 14% wind)
• CFD-MP; lower LF, higher LCOE, higher CFD

Optimal frameworks and RES share?
• Trade-off between RES share and costs is not linear

Surplus risks?• Only with ‘New Capacity’ scenarios• Random PV & wind generation in Matlab (10 000
patterns), based on Elia • ‘Must-run’; biomass (MP), CHP & nuclear• Compared to demand variation in 15 min intervals• Demand (15 min) <-> (RES + Must Run)• Export capacity of 3 500 MW; surplus of 3 000 is
problematic• DSM (to increase demand); here not included

Conclusions 1
![Page 43: The price of energy security in depressed electricity markets; the case of Belgium](https://reader035.vdocuments.us/reader035/viewer/2022062807/56815037550346895dbe3403/html5/thumbnails/43.jpg)
Conclusions 2• To secure 5% RM, cumulative subsidy costs up to 2030
vary between € 21 and € 41 billion• Smart policy choices will lower costs for society, even at
relatively high RES shares• Market participation by RES is essential to facilitate
further expansion of RES• DSM lowers costs / Old thermal; limited relevance• limitations of this analysis; capacity payments as
institutional challenge (end of EOM?), recovery of demand, delocalisation energy-intensive industries, evolution of interconnection, arrival of smart grid, share of electric vehicles by 2030, EC climate policies,…
